Eiver, Cape Breton, contain several species of trilobites, 

 which show that these measures are in the upper part of 

 the Olenus Zone, or Lingula Flags of Great Britain. The 

 species observed «w ere the followiug: — Peltura scarabeoides, 

 Wahl ; Sphceropthalmus alatus, Boeck ; and Agnostus pisiformis, 

 Lin. There is also a small Lingulella similar to that which 

 characterizes the Upper Flags of the St. John Group, and 

 also an Orthis, similar to Orthis lenticularis, Dal. 



In a small collection of fossils sent to him by Mr. Howley, 

 of the Geological Survey of Newfoundland, a number of spe- 

 cies not heretofore reported from that island were observed. 

 With the aid of these and the description of other species 

 given by the late Mr. Billings and by Mr. Whiteaves, Mi*. 

 Matthew is able to classify rougbly the Cambrian horizons 

 of that island. 



HOEIZON OP PABADOXIDES KJEEULFI. 



The oldest fossils appear to be those of Topsail Head and 

 Brigus in Conception Bay. Mr. Billings describes from 

 these places: — Agraulos strenuus, Bill.; Stenotheca paupera, 

 Bill. ; and Ijrfiidea, allied to I. bella. To these may be added 

 the following as characterizing the limestones of Topsail 

 Head : — Paradoxides Kjerulfi, Linrs. : Selenopleura, sp. ; 

 Ptychoparia. sp. ; Stenotheca, sp. ; Straparollina ? sp. ; 

 Jffyolithes Micmac. 



HOEIZON OP THE CONOCOEYPHEES. 



Manual River, a small stream near Topsail Head, appears 

 to give the next horizon, for Mr. Whiteaves chronicles from 

 this place : — Microdiscus punctatus, Salter ; M. JDavjsoni, 

 Hartt ; Agnostus Acadicus . Hartt ; Conocephaiites (Liostra- 

 cus) tener, Hartt; C. (Conocoryphe) Baileyi, Hartt; and C. 

 {Ptychoparia ?) Orestes, Hartt. Of these species the second, 

 fourth and fifth do not range as high in the Cambrian beds 

 of Acadia as the others, and it is possible that the collec- 

 tions examined may have been from two horizons. The 

 assemblage of species, however, may be taken to corre- 

 spond with those of Band C. of the Acadian area. In a 

 fragment of shale from the same locality, the following
